The 2008 car accident that left bassist Chi Cheng brain-damaged (he died in 2013) nearly broke them. They channeled that grief into Diamond Eyes (2010)—a surprisingly life-affirming, heavy album that reinvented them again. Since then, with Sergio Vega (and now Fred Sablan on bass), they've only deepened their sound, with 2020's Ohms being a late-career high point.
Deftones are a band of contradictions—aggressive but sensual, heavy but ethereal, ugly but beautiful. They created a sound that no one has successfully copied, and they've become the favorite band of people who usually hate metal. That's the "interesting piece."
What specifically drew you to them? A particular song or album?
